Polymorphism of poly(vinylidene fluoride) induced by poling and annealing
نویسندگان
چکیده
2014 In stretched poly(vinylidene fluoride) films, the transition from unpolar 03B1-form to a polar form (03B1p) is produced by pohng at 80 °C by an electric field of 1 MV/cm. This oriented form has the same lattice constants as 03B1-form but is associated with extra diffuse reflections. This form and the diffuse reflections disappear by annealing above 170 °C and give an oriented and more stable form (03B1’) in which the chain has the T3GT3Gconformation.

Performance of Chemically Modified TiO2-poly (vinylidene fluoride) DCMD for Nutrient Isolation and Its Antifouling Properties
The surface properties of TiO2-PVDF nanocomposite membranes were investigated by incorporating different chemically modified TiO2 nanoparticles into the poly (vinylidene fluoride) (PVDF) matrix. The nanocomposite membranes were prepared via dual coagulation bath diffusion and the induced phase inversion method. The membrane surface morphologies were investigated by using SEM and AFM and related...
متن کاملEffect of poling state and morphology of piezoelectric poly(vinylidene fluoride) membranes for skeletal muscle tissue engineering
This work reports on the influence of polarization and morphology of electroactive poly(vinylidene fluoride), PVDF, on the biological response of myoblast cells. Non-poled, ‘‘poled +’’ and “poled-“ -PVDF were prepared in the form of films. Further, random and aligned electrospun -PVDF fiber mats were also prepared. It is demonstrated that negatively charged surfaces improve cell adhesion and ...

متن کاملFormation of Poly(vinylidene fluoride) Nanofibers Part II: the elaboration of incompatibility in the electrospinning of its solutions
Poly(vinylidene fluoride) (PVDF) fibers with two molecular weights were prepared via electrospinning process. In this process, the concentration of spinning depended drastically on the gelation process. Also, it was experimentally smaller than obtained concentration in the solution entanglement number approach (SENA). Proof of this incompatibility was explained by the properties of PVDF a...
متن کاملIsothermal Melt Crystallization Kinetic Behavior of Poly (vinylidene fluoride)
Isothermal melt crystallization kinetics of PVDF was investigated by differential scanning calorimetry. Thin PVDF film has been fabricated by the solvent casting technique using dimethylformamide (DMF). Then, the samples were melted and subsequently crystallized in the range of the crystallization temperature (Tc) between 138 and 145 °C. The crystallization kinetics was derived from Avrami equa...
